The present invention is related to an aqueous cleansing compositionespecially for keratin fibres such as human hair with shine enhancingeffect.

Cleansing compositions have been known for many years. Many patentapplications and scientific publications deal with such compositionsaiming at cleansing and especially improving conditioning effectswherein shine enhancing of human hair has gained particular attention.Although this, there is still need for improvement.

Hair shine improvement has been one of the main areas of development.Hair shine is very much related to the surface structure of hair andthis varies very much with the degree of damage either by environmentaleffects or chemical treatment of hair such as permanent shaping oroxidative colouring. Although consumers with healthy non-damaged hairare generally satisfied with hair shine, shine of damaged hair isusually found to be unsatisfactory. There have been studies aimingimproving shine of especially damaged hair.

Present inventors have surprisingly found out that a cleansingcomposition comprising one or more surfactants and at least one arylatedsilicone cleanses hair thoroughly and improves shine and conditions hairexcellently in terms of combability, elasticity, smoothness andsoftness.

Accordingly the subject of the present invention is an aqueous cleansingcomposition especially for keratin fibres such as human hair comprisingat least one anionic surfactant, at least one non-ionic surfactant andat least one amphoteric surfactant at a total concentration of 5 to 50%by weight calculated to total composition, and at least one arylatedsilicone at a concentration of 0.001 to 2.5% by weight, calculated tototal composition.

% by weight Sodium lauryl ether sulphate 8.0 Cocoyl polyglucoside 3.0Cocamidopropyl betaine 3.0 Sodium lauroyl glutamate 1.0 Trimethylpentaphenyl trisiloxane 0.2 Polyquaternium-10 1.0 Citric acid/sodiumhydroxide q.s. to pH 5.5 Preservative, fragrance q.s Water to 100

For comparative purposes the above composition was also produced withoutarylated silicone, Trimethyl pentaphenyl trisiloxane.

The above composition was prepared by combining surfactants with part ofwater and subsequently adding Polyquaternium-10 solution in waterprepared at around 70° C. Afterwards, Trimethyl pentaphenyl trisiloxanewas added and preservative and fragrance was mixed. Finally pH wasadjusted.

The performance of example was compared to the comparative compositionin a half side test with 10 volunteers. Hair of the volunteer wasdivided into 2 and washed with example 1 and comparative compositionusing according to hair length 4 to 6 g of the product. After rinsingboth sides were evaluated by at least 2 hair dressers and by thevolunteer in towel dried and dry state. It was found that the sidewashed with example 1 had more elasticity, more volume and body andespecially significantly more shine. The preferences were generally 8 to2 and for shine 10/0.

Similar results were observed with the examples below.
